For over 120 years, the City of Marshfield has taken an active role in maintaining the quality of the local environment. Since 1880, the City has provided wastewater collection and treatment. Over the years, the City has continued to improve its collection and treatment system to meet evolving state and federal regulations and a growing population.
Below is a timeline of improvements to the Marshfield wastewater system.
Original collection and treatment facility is built.
Two Imhoff tanks are installed. One tank was installed on South Roddis Avenue and one was installed at Braem Park.
Braem Park site is abandoned and another Imhoff tank, primary clarifier and trickling filter is added to the facility on South Maple Avenue.
The Maple Avenue site is abandoned and a new wastewater treatment plant is constructed on South Vine Avenue.
The treatment plant is expanded to comply with Federal regulations.
The sewer collection system rehabilitation is completed.
The wastewater treatment plant is upgraded to include tertiary level of treatment.
Twin, two-million gallon biosolids storage tanks were built on the site of the future wastewater plant, located southwest of Galvin Avenue and Yellowstone Drive.
The South Vine Avenue facility was abandoned. A new facility located at 2601 East 34th Street was built to meet current community needs and revised State regulations.
The Northeast Lift Station, located south of the McMillan Street and Galvin Avenue intersection was upgraded with new pumps and control to reduce plugging from wipes.
The facility underwent two major upgrades:
- On June 24, 2016 the wastewater treatment facility switched over to Biological Phosphorus removal operation from that of Chemical Addition to remove harmful nutrients.
- 8th Street Lift Station, located at 8th Street and Hawthorn Avenue was completely upgraded from a wet well - dry well station to a submersible pump station which eliminated the confined space entry and modernized a station that was over 40 years old.
A pair of concrete tanks were installed at the wastewater treatment facility to accept high strength waste. The system also included odor control and a computerized feed system to add the waste when it was most beneficial to the atural bacteria that feed on phosphorus.
The Mannville Lift Station, located at the intersection of Highway 13 and Mann Street was completely upgraded from a wet well - dry well station to a submersible pump station. The upgrade eliminated the confined space entry and modernized a station that was over 40 years old.
